This invention relates to improvements in book-making machines, and moreparticularly to the filler in cooperative relation with the ad hesivelyapplied cover, one object of the in-. vention being the provision of apalette'of A further object of this invention is the" provision of asectional palette for book-making machines in which yi'eldingly mountedbars or extensions are provided, two to each section, and so constructedand arranged as to insure the feeding of'the fillers toa flexible Icovering' sheet to provide stifi or'flexible backs for books, saidsections being so constructed and arranged as to render the pal,ctteadjustable-both longitudinally and transversely to accommodatefillers and covers of different areas. I D i I In the accompanyingdrawings I the carrying arm being shown in section.

Referring to the drawings,-the numeral 10' designates a laterallyswinging arm of the book-making machine which has the flanged head 11for supporting the palette P. F and F indicate the filler, Othe flexiblecover sheet, and L the lining strip.

The palette consists primarily of four members 13, 14, and 16,respectively, each one of which is substantially'identical in conpalettewhich is used in placing the" Yatlve positions and in pairs.

Figure 1 is a top plan view of the palette,

i in turn, clamp the grooved portion .11 of the and 30, to the Irespective bars 26 and 27. Thus, in this way, 1 the four sections areconnected by the i restruction, so the description of one will sufficefor all, In order to connectthe respective sections 13 and 14-and 15 and16 for longi- I tudinal adjustment, I employ'the two bars pair, thelower edge I l7 and 18, one to each of thebars being provided with a rib19 for sliding in the groove 20 of the respective sec tions so that thebolt 21 with its nut 22 may adjust-ably attach the sections in thei'relprovided with a hose-receiving projection 23 and with a rubbervacuum cup as 24, so that Ea'ch section is I the filler and lining stripmay be suctionally I held in'place during the movement from the;

pile to and upon the cover sheet C. These nozzles 23 areconnected by a.flexible hose 25to the main carryinghead 10 in the usual v In. orderto'p rovide a lateral or transverse;

adjusting. means for the respective sections of the palette, the twobars .26 and 27 are connected by means of screw bolts 28 and 2,8- to thebar 18, while the free ends rest upon the i I bar 17 and'are connectedthereto inadju'stable relation by means of the bolts 31 wh member 10, asindicated at 29 spective members 17 and 18 and 26 and 27 to be held infixed adjusted relation.

Each section has projecting 34. The-lug 33- is provided with an openingv35 therethrough, which is alined with the opening 36 of the .lug 34,while the lug 32 I I I from the. up per surface thereof the three lugs32, 33 and and is stopped in its outward movement by means of thescreworbolt39, the spring-40- being mounted upon the pinandexertin'g a Ipressure on the outer face of thelugx33 and cooperating with the springv42. mountedupon the sliding pin 41 to hold the presser bar 43 outwardlyand? awayfrom'the outer 1 face of its respectivesection. The lugs 33 and34 are provided with the openings '44 I and 45 which are below and'atright angles to the respective openings 35 and. 36 and;

have 'slidably mounted therein the pins '46 and 47 which are attached toand carry the short presser bar 48, a slotted limiting lug.-

49 being carried'by the bar and cooperating .cover C away from with thebolt 50 to slidingly attach it to the section 13. A sprin 46 is mountedupon each of the pins 46 and 47 to holdthe presser bar 48 outwardly andaway from its section; The vertical ribs 51 and 52 are formed in--tegral with and in spaced relation upon the V W hen the sections are a jto take the lining strip or back lining section L or are in the positionas shown in Figure 1, the space between the respective sections isfilled in by the lining strip lifting sections 53 and 54, the same beingconnected to the under Each section 5354 is also provided with thesuction device .18, which, when in use, 1s

- clip 56 being composed of side of the bars'17 and 18, respectively, bymeans of a screw 55, one to each section.

connected to the usual flexible hose connections 25, and thus permitsthe present palette to simultaneously elevate two fillers F and F andone lining strip'L.

Inorder that two adjoining bars 43, or two adjoining bars 48 may be madecontinuous,

respectively,there is provided a spring clip or connector 56 which isadapted to be placed either over the upper edges of alined presserbarsor the low r edges as the case may be and the occasion warrant, thesaid spring metal bent upon itself and havinga tendency to griptherespective bars upon which it is attached and spanning the same, as

pressed bed illustrated in Figure 5, so as to make 'a' continuous bar sothere can be no space between the ends thereof that mightpermita puckeror inward fold upon the filler F during the movement of the barsinwardlv.

When the present device is in use it is similar to the palettes shown inthe various patents toJacobs, and that to Satenstein, No. a

springs which yieldingly hold the presserbar 1,328,767 but brieflystated, it is as follows:

i The flexible cover C is placed upon a-spring- (not shown) with theusual edgeforming members 60, onlv one set of which is here shown, in apositionto permitthe pal- V ette with the respective presser bars 43 and48 fully extended to pass therebetween and place the filler F upon thecover C. When the filler is below the members'60, the mem bers 60 aremoved inwardly, engaging the upturned edges of the cover C and pushingthem over and upon the upper side of the filler F, and at the same timepushing the respective presser bars againstthe action of the springs, asis the usualpractice, or in a sufficient distance to permit theedge-forming portions 60 to press the Lip-turned edge downwardly uponthe filler F and its inner edge thereof free from'the outer edges of therea sheet of flexible spective presser bars, and then the edge-formingmember upon the remaining two sides are moved in to complete theoperation.

It is evident from the foregoin description that-with a palette madeaccorc ing to the present invention a book-making machineis adaptablefor use upon the varioussized book covers with flexible or stiff fillersand lining strips for the back, and also carrying the lining stripsimultaneously with the filler so that when the present palette hascompleted its operation with the lateralplungers of the book-makingmachine, the complete bookback, including two fillers with or i ithoutthe back lining strip, is completed, and is held during the formingoperation in a flat nonwrinkled position so as to'insure'a complete andneat article. i

In practice I have found it desirable to provide some means forpreventing the puckering ofthe cover at the corners and at the same timeto improve thefolded and finished article at this point, and to this endI have em: ployed the construction as illustrated in Figure 7 and in themethods as illustrated in Figures 8 and 9. The bars 43 each have mountedupon one end thereof, the end nearest the corproper straight-linemovement between the parts. The spring'68 is'disposed and mounted tohold the extension outwardly with, its right-angledhead 69 in thedesired position forfcooperating withthe overlapped end of the presserbar- 48, as illustratedin the steps in Figures 8 and 9, Figure 8 showingthe device in the position it assumes at the initial movement ofthe'palette down between'the folding plungers, and Figure 9 when there-' spective bars 43 and 48 are brought into coopcrating position, theextension 65 clearly clos ing the gap at the corner;

In order "to provide an alternate .for the outwardly,- I have shownin'Figure 10 a vacuum or "suction means, the plunger 69 in this instancebeing operated upon by afsuction or vacuum to hold the presser bar 43yieldingly outwardly As shown in Figure 11, pressure is employed insteadof suction, and inthis instance, the'plunger 7 0 is held outwardly fromthe pressure at the rear thereof;
